The only drawback, but a bit of taste is: As with many cases, the buttons on the edge (Power button, volume keys) are concealed by buttons of shell that are not usually as sensitive as the device itself You have here already in a very certain. Angle press so that the device also reacts. You also not noticed that you have pressed a button - so from the feeling - once the unit times not respond.
(May also be that this fact depends on the processing of individual cases, but for me that was the reason to return the envelope and to take up a Hama-shell, since the keys are in fact recessed from the shell.)
FIX: A request for Handynow revealed, however, that there is also a variant with recessed buttons. This was replenished me a gesture of goodwill, free of charge. With recessed buttons there are in this envelope nothing to fault (+ a star more)
